Roll number and rolling schedule are the important parameters affecting the quality of steel bar straightening，when domestic manufacturer design the straightening equipment, these two parameters design basic is by analogy, so it is necessary to study these two parameters. This paper calculated the straightening roller to obtain reasonable roll number; next step quantitative calculate to obtains the theory rolling schedule, in the meantime actual measurement to obtains the practical rolling schedule of the same equipment；then based on rigid-flexible virtual prototype technology to build straightening system dynamics model. At the theory rolling schedule, and the practical rolling schedule for steel bar straighten emulation, obtained straightness and deviation of different diameter steel bar after straightening. By comparison and analysis the simulation results, we obtain the reasonable roll number and rolling schedule. In this paper, this method have reference value to design the roll number and rolling schedule for similar straightening equipment. |
